linux-toradex.git/fs/xfs/xfs_vnodeops.c, branch v2.6.19-rc2 Linux kernel for Apalis and Colibri modules [XFS] Really fix use after free in xfs_iunpin. 2006-09-28T01:06:03+00:00 David Chinner dgc@sgi.com 2006-09-28T01:06:03+00:00 f273ab848b7cbc0088b0ac7457b3769e6566074e The previous attempts to fix the linux inode use-after-free in xfs_iunpin simply made the problem harder to hit. We actually need complete exclusion between xfs_reclaim and xfs_iunpin, as well as ensuring that the i_flags are consistent during both of these functions. Introduce a new spinlock for exclusion and the i_flags, and fix up xfs_iunpin to use igrab before marking the inode dirty.
